I'm seeing a couple of problems here - and I have a question. First of all, drooping leaves come from either too much water or not enough water... most will tend to overwater their plants and this is the quickest way to kill pretty much ANY kind of plant. I don't see the amount of water you're giving them in your diary but I'm willing to bet you're giving them too much. Wait until the pot is SUPER lightweight before giving them a watering or a feeding...
One problem I'm seeing is that you are giving them WAY too much grow nutes for their age! Autos, in flower, do not need and do not like a lot of nitrogen which is present in the grow nutes. Cut them WAY back or cut them out entirely... go only with your bloom nutes...
You had a question I'm just seeing now about the yellow leaves at the bottom... they are another indication of nitrogen toxicity and yes, cutting them off was fine BUT I don't think it addressed WHY they were yellowing... So at this point, with everything you've got going on, I would suggest that you need to check the PH of your runoff. FIRST, dry the plant out then give it enough of a water that you've got about 20% running out the bottom - scoop some of that runoff up and find out what its PH level is... if it's not within a range of 6.0-6.5, you'll need to do more work (msg me at that point and I can help you out).
All in all, you've got a couple of problems but none that are unsolvable... it's just going to take a little bit of time and patience and they'll be just fine!
Good luck - and again, msg me if you want.
